title: Effect of acetone on the toxicity of atrazine towards photosynthesis in Anabaena.
abstract: The effect of acetone on the toxicity of atrazine towards photosynthesis in the blue-green algae Anabaena inaequalis, A. variabilis and A. cylindrica was investigated. The order of sensitivity to atrazine was A. inaequalis greater than A. variabilis greater than A. cylindrica. Acetone and atrazine interacted additively, antagonistically, and synergistically, depending upon the concentrations of acetone and atrazine used. The EC50 of atrazine towards photosynthesis was dependent upon the type of solvent-pesticide interaction.
